We transplanted more than 50 Hemlocks beginning in the early 1990s on our property. The Woolly Adelgid showed up about four years ago. I noticed the infestation on the very lower branches in the early spring of 2019 of a few trees. I sprayed them with a soapy mix (off the shelf) which seemed to help. But, I did research and learned about the chemical to treat them (derivative from nicotine, imidacloprid, as I understand). I wanted to experiment rather than dig trenches or attempt spraying. So, I sprinkled the approximate amount of chemical around the trees about two to three feet away from the trunk (no digging). Using water from a well on my property, I set-up a sprinkler to wet the ground around the trees (about 15 gallons per tree). There was zero run-off from the watering process. Anyway, today, (September, 2023) my trees are disease free. I plan to re-treat them in the spring of 2024.
